(11) IR Input An IR repeater can be connected to this mini-jack (12) 12V Trigger When this 2-conductor mini-jack is connected, the amplifier remains in power-off mode until the trigger is applied The correct trigger is +12V on the tip of the connector relative to the grounded sleeve (13) RS-232 In Use this port to communicate with an RS-232 controlled touch panel system See Appendix A for an explanation of the use of the serial port, available commands and their formats (14) Signal Sensing Auto On/Off Switch With this switch in the standby position, your system can be safely left with the main power switched on continuously The tactile amplifier will turn itself on automatically when an audio signal is present If no signal is present for approximately 10 minutes, the unit will switch to standby mode While in standby mode, your t a c t i l e amplifier will draw very minimal power This function can be disabled by leaving the switch in the always on position (15) Speaker Level Input Terminals If you do not connect the amplifier to your receiver using the line input/lfe input connection (Item 10) connect these input terminals to the speaker output terminals of your amplifier or receiver If you use this method of connection, make sure to select the large speaker option in the receiver s speaker set-up menu Also, select the option for no subwoofer This will make sure all bass and LFE information is fed to the speaker outputs and be received by your amplifier Note: Using both speaker terminals and the line level inputs is not recommended, as this may damage the amplifier or your receiver (16) Speaker Level Output Terminals These connections send a crossed-over speaker-level signal to the front speakers When connected in this fashion, your satellite speakers will be crossed over at 80 Hz This removes the task of reproducing frequencies below 80 Hz from your satellites, enabling them to do a better job reproducing high frequencies You may also connect your satellites directly to your receiver or amplifier along with the subwoofer if you wish to bypass this crossover An example of a speaker-level connection is shown in Figure 3 5
Speaker-Level Signal from Source 1 2 80 Hz and Above to Satellite Speakers 3 4 Figure 3: Speaker-Level Connection (17) and (18) Actuator Connection 5-way Binding Post Terminals Connect the output terminals to the Actuators being controlled by the amplifier connect a max of two Actuators to each red/black pair of output terminals Caution!!! To avoid damage to your amp and Actuators, be sure to maintain correct polarity when making all speaker connections; red (positive) to red, and black (negative) to black Be sure that all connections are tight, and that there are no loose strands or frayed wires (19) Power Cord Adapter Connect the detachable power plug to this male interface connection The detachable cord allows for easy replacement should the original become damaged (20) Main Power Switch Press the POWER switch to the ON position to activate the amplifier If the unit is to be left unused for an extended period of time, move this switch to the OFF position to prolong the life of the amplifier (21) Fuse If the unit is not functioning, check the fuse If the fuse is blown, replace with an identically rated fuse If the fuse blows again, refer the unit for service 6
R e a r Pa n e l C o n n e c t i o n s D e ta i l e d E x p l a n a t i o n The amplifier is equipped with both speaker-level and line-level inputs Use the RCA/Phono type INPUT jacks when connecting from a pre-amp, signal processor, or line-level crossover The SPEAKER LEVEL INPUT jacks connect directly to the speaker outputs of an integrated amplifier or receiver Your amplifier section will notice no additional loading effects when you use these inputs because of their high impedance Note: Do not use both the RCA/Phono INPUT connections and SPEAKER LEVEL INPUT connections simultaneously A B O U T L O W - P A S S F I L T E R ( L P F ) All of the amplifier inputs sum the left and right channels together and the resulting signal is passed through an adjustable low-pass crossover before being amplified The crossover control allows you to adjust the upper limit of the Actuator s frequency response from 30 to 160 Hz The Actuator s response will begin rolling off above the frequency you set this control to The slope is 24 db/octave You should set the crossover frequency to obtain a smooth and seamless blend with the subwoofer and the main speakers in your system Adjusting the LPF to the preferred setting will ensure that desirable low-frequency motion is present, while undesirable high-frequency content (such as motion from human voices) is not Proper adjustment of the LPF will allow your motion experience to most closely resemble a real-world sound experience Start with the LPF set to 160Hz Reduce the frequency setting if unwanted high frequency content such as voices is present during testing Increase the setting if you feel that desirable content is being unnecessarily removed Most receivers and processors provide a menu option in which you can characterize main speakers as large or small speakers This affects the bass signals passed to the main speakers We r ecommend in most cases setting the main speakers to small, despite their size and frequency response characteristics, allowing all multi-channel bass and LFE signals to be passed to the D i s a b l i n g t h e L o w - P a s s C r o s s o v e r ( S u b w o o f e r D i r e c t ) If your receiver/processors provides a crossed-over signal to the subwoofer you may want to bypass the amp s low-pass crossover To do this, depress both the Crossover UP and -- Crossover DOWN buttons simultaneously The numeric LED will show indicating that the low-pass crossover has been defeated To reactivate the low-pass crossover, simply push the Cr ossover UP or Crossover DOWN buttons A W O R D A B O U T Y O U R H O M E T H E A T E R R E C E I V E R S C R O S S O V E R A N D T H E C - 6 0 2 A M P L I F I E R S C R O S S O V E R Your Crowson amplifier is designed to operate using the full range audio signal for input when using the built-in crossover Many home theater processors/receivers have a subwoofer out jack that performs this same function and are designed to be used with a powered subwoofer In these installations, you may want to bypass the crossover in either the processor or the Crowson amplifier as described above However, in some cases you may want to use B OTH crossovers If you choose to do this you should stagger the frequencies, (ie, 120 Hz subwoofer, 80 Hz processor) for best results 7
A W O R D A B O U T I N T E R C O N N E C T C A B L E S When connecting the amplifier to your subwoofer using the speaker level connections, use a high quality speaker cable It is recommended that you keep the length of cable as short as possible to avoid any potential external interference problems When connecting the amplifier to your actuators, use quality speaker cable that is at least 18-gauge Be very careful to avoid any loose or frayed strands that could result in a short, causing a dangerous condition and possible damage to your unit Cables of extremely large size are typically not required Extremely large gauge wire may not properly fit in the binding posts, resulting in a poor connection and possible short circuits Caution! This amplifier is an electronic device Do not place the amplifier next to sources of heat such as furnace registers, radiators, etc Likewise, do not place the amplifier near sources of excessive moisture such as evaporative coolers, humidifiers, etc The power cord should be routed in such a way that it will not be walked on, pinched or compressed in any way that could result in damaging the insulation or wire 8
U s a g e This section addresses day-to-day usage of your amplifier R e m o t e C o n t r o l The features of the remote control are listed below POWER This button forces your amplifier unit into standby mode The power LED turns amber, the numeric LED shuts off, and the amplifier puts out no power The unit will remain in this mode until the POWER button is pressed again To fully deactivate (ie power down) the unit, use the main power switch on the back panel Note: The master power switch on the rear panel must be on in order for the front power button to function MUTE This button mutes the Actuators s output The LED on the amplifier will show 00 if the unit is muted To unmute the Actuators, press the MUTE button again and the original volume setting shows on the LED POWER 0 270 90 180 LIGHT NIGHT MUTE + 1 2 3 4 - Figure 4: Remote PHASE These buttons allow you to optimize the Actuators performance for the seat location and listening position Play some bass-heavy music While listening, push one of the four phase buttons, listen and feel for a few moments, and then press the next phase button In most installations, one of the four button positions will offer a better blend with the subwoofer and speakers Selecting the correct phase position is that easy The LED will show the phase selected by showing PH followed by the phase number: 0, 90, 180 or 270 LIGHT If you wish, you can deactivate the numeric LED on your amplifier To do this, press the LIGHT button on your remote To reactivate the LED, press the LIGHT button again NIGHT Night mode limits the maximum dynamic output of the motion system for late night listening or to be more considerate of close neighbors Press the night button to turn the night mode feature on or off Activation of night mode causes n to appear briefly on the display When night mode is deactivated, the display shows n off and then returns to normal function INTENSITY (VOLUME) CONTROL The intensity control adjusts the intensity of the tactile motion effect Set the intensity to preferred levels When pressing up or down, the level change is shown on the numeric LED on the front panel 9
WARNING: Some manufacturers preset their receivers with the Sub-Out channel signal at a minimum level It is very important to verify that your receiver Sub-Out channel is set to the same output level as your front right and left channels Refer to your receiver manual for the individual channel level adjustment procedure If your receiver Sub-Out channel is set too low, the Tactile Motion System may appear to have a weak output, it may sound noisy or distorted, and the Auto On/Off feature may not operate properly Note: The intensity (volume) can also be adjusted via the volume buttons on the front panel of the amplifier These buttons have the same effect as pressing the up and down intensity buttons on your remote PRESETS There are four presets, consisting of Movies, Music, Flat, and Games As a preset is chosen, the preset is shown on the numeric LED as P1 for preset 1, P2 for preset 2, etc The presets provide the following characteristics for tactile reproduction: Movies: Music: Maximum output and impact for explosions and other action adventure movie content Provides the driving bass found in today s rock music Flat: The tightest and cleanest effect The flattest frequency r esponse of the four presets Games: Maximum power available for the impact of video games Each preset has its own characteristics with respect to volume differential and a single contour equalizer C a r e o f yo u r A m p l i f i e r Do not use any harsh detergents or chemicals to clean the chassis Abrasives, detergents, or cleaning solutions will damage the finish on the chassis We recommend using a damp cloth to clean the front, back and sides Do not allow any liquids to enter the chassis During normal conditions, the amplifier may be left on continuously without any problems If you plan to leave the unit unused for an extended period of time, we recommend that you turn off the unit by the master power switch on the rear panel 10
T r o u b l e s h o o t i n g a n d S e rv i c e B efore seeking service for your amplifier or actuators, please re-check all systems Following is a simple troubleshooting guide to assist you 1 Verify that the unit is plugged in and power outlet used is active 2 Is the power switch on? 3 Is the unit receiving an input signal from your receiver or processor? 4 Have all controls on the amplifier (intensity, crossover, phase, etc) been properly set? 5 If the unit has been running at high levels, one of the protection circuits may be engaged Has the amplifier overheated? 6 Has the power button been depressed on the remote? 7 Is the remote non-responsive? We recommend replacing the batteries in the remote If the protection circuitry is active, the unit may cycle on and off until operating parameters return to normal Under more serious conditions, the unit may shut off completely Normal operation should return upon cooling, but you may be required to turn the power off and then on again to reset the unit The following conditions require service by a qualified technician: 1 The power cord has become damaged 2 The unit does not appear to operate normally or exhibits a marked change in performance 3 The unit has been exposed to water 4 Some part of the chassis or circuitry is physically damaged 11
